Nearly four years after Mclaren dubiously claimed a sub-7 minute Nurburgring lap time for the original P1, they've set a new production car lap record with the P1 LM. And this time around there's indisputable video evidence.

The McLaren P1 LM's lap time of 6:43.22 bests the previous record set by the Lamborghini Huracan Performante (6:52.01), and the lesser known record lap (6:45.90) of the NIO EP9, an all-electric production supercar.

The P1 LM is a pared down track special. It cuts nearly 400 lbs. off of the standard car thanks to lightweight race seats, an Inconel exhaust, removal of the air jack system, and other weight reduction measures.

In additional to weight reduction, the P1 LM benefits on track from a 40% increase in downforce courtesy of an all-around more aggressive aero package.

​You might be thinking that the P1 LM as a "production street car" is a bit of stretch… Fair enough.

But to McLaren's credit, and to contribute some veracity to the production street car label, they did drive to and from the 'Ring in the process of setting the lap time, which is just plain cool.

Also, they've manufactured (and sold) 5. So yep, criteria met; the P1 LM is not much different than a Honda Civic.

As usual, the "tire factor" is an underreported element of the story. Street legal track tires are the fundamental component that make these production car lap times possible.

In the case of the P1 LM and also the Huracan Performante, Pirelli's P Zero Trofeo R was assigned traction duties.

So give driver Kenny Bräck some credit not only for the lap time, but enduring the ~900 mile roundtrip journey to and from the 'Ring. We know that the Trofeo R can be an adventure on rain-soaked roads as pictured above, and it reminds you with every audible revolution that it's a dedicated performance tire as well.
